Analysis of sustained release of BSA-FITC loaded inside GA-MS (n = 3, n represents number of GA-MS sample groups)

(A) Confocal fluorescence microscopy images of GA-MS containing BSA-FITC. The fluorescence intensity of images decreased with the extension of immersing time.

(B) Fluorescence microscopy images converted to interactive 3D surface plots.

(C) Distribution histograms of gray value distribution of interactive 3D surface plot converted from confocal microscopy images.

(D and E) Means and standard deviations of the gray levels after 0, 3, 9, 21, and 36 h.

(F) Cumulative release of BSA for the 457 ± 3, 361 ± 4, and 246 ± 6 μm particles of GA-MS after 0.5, 1, 2, and 3 h of immersion in DPBS.
